SYNOPSIS

9       #include <curl/curl.h>

12       enable);

DESCRIPTION

15       Pass a long. If the value is 1, it tells curl to send  a  PRET  command
16       before  PASV  (and  EPSV).  Certain FTP servers, mainly drftpd, require
17       this non-standard command for directory listings  as  well  as  up  and
18       downloads  in PASV mode. Has no effect when using the active FTP trans‐
19       fers mode.
